## Cons

- Might lead to a greasy or crispy feeling if over-applied or if not compatible with other hair products

- The leave-in serum has a thick consistency that can be hard to apply evenly without over-application

## Bottom Line

This serum offers a great balance of nourishment and shine without leaving hair greasy or weighed down—ideal for those with oily or fine hair looking for a natural, non-greasy product. However, if you have long, delicate, or very fine hair or are prone to scalp dryness and irritation, you might want to explore alternatives.
